Title: Production of multicore fiber
Inventor: MATSUDA HIROO
IPC: G02B6/04
Filed: 1979-06-26
Abstract: PURPOSE: To prevent the change in the relative size of outside diameter and core diameter, shape, etc. and obtain sufficient strength by filling fine glass powder or the like in the spacing between the bundle of fiber base materials and the glass pipe to be put on at the time of stretching.  
     CONSTITUTION: The sectional shape of each fiber base material 1 is ground to a hexagonal shape and these fiber base materials 1 of a hexagonal shape are so disposed and bundled as to become dense with each other and if there is any spacing between the bundle of the base materials 1 and the quartz glass pipe 3 to be put on at the stretching, the quartz glass rods 5, quartz glass fibers, fine glass powder or the like meeting the shape of the spacing is filled therein at the time of stretching and reducing the diameter of the same, after which while being evacuated from the other end of the closed glass pipe, the stretching and diameter-reducing are done. By filling the filler at the time of stretching and diameter-reducing this multicore fiber from the base materials 1, the change in the relative size of the outside diameter and core diameter, position and shape may be prevented and the sufficient strength may be obtained.

Title: Manufacture of multilayer ceramic circuit board
Inventor: IMANAKA YOSHIHIKO
IPC: H05K3/46
Filed: 1990-03-30
Abstract: PURPOSE:To improve green sheets in adhesion between them so as to enhance a multilayer ceramic circuit board in number of layers by a method wherein solvent is applied onto the surfaces of the green sheets which contain ceramic powder and resin, and the green sheets are laminated. CONSTITUTION:Solvent is sprayed onto the surface of a green sheet which contains ceramic powder and resin to make resin chemically flexible so as to fuse it into one with other resin contained in other green sheets, and the green sheets are laminated and thermocompressed so as to come into close contact with each other. Or, the surface of a green sheet is made to contain more binder and plasticizer so as to enable green sheets to be easily bonded together. By this setup, as green sheets are enhanced in adhesion at laminating, a green sheet laminate of integral structure can be obtained even if it is increased in number of layers.

Title: Control device for sound from engine and its device
Inventor: SHINADA MASAFUMI
IPC: F02M35/12
Filed: 1990-03-30
Abstract: PURPOSE:To emphasize good feeling sound by selecting different phase difference in a phase difference imparting process, and thereby freely selecting attenuating or emphasizing engine generating sound in a control device for engine generating sound including the phase difference imparting process which changes the phase of an electric signal due to an oscillation of air passing through an engine. CONSTITUTION:A phase control circuit 20 is provided, which inputs the detected signal V1 of a revolution detecting sensor 10, and the noise signal V4 of a noise sensor 11 such as a microphone and the like disposed on an inlet air duct 7. In addition, change- over switches 4 and 5 for a first mode and a second mode are disposed on an instrument 3 within a cabin, and respective input signals V2 and V3 are also inputted into the phase control circuit 20. And when change-over to the first mode is made, high frequency components included in noise signals are removed, only band frequencies other than high frequencies are allowed to pass through being reversed in phase, signals to which phase difference is imparted, are forwarded to the inside of an air cleaner by means of a speaker, and let them interfere with generated sound so that they are thereby attenuated. On the other hand, when change-over to the second mode is made, noise signals of specific frequencies included in the band frequencies are processed in such a way as to be left within the cabin as good feeling music sound.

Title: Scanning circuit
Inventor: TAKENO MINORU
IPC: G01R31/28
Filed: 1985-04-18
Abstract: PURPOSE:To make scanning FF adaptable even to a non-synchronous circuit, by selecting the input of scanning FF by providing a data selector. CONSTITUTION:A data selector 11 selects data Data 1 and a non-synchronous clock NSCK 1 corresponding to such a mechanism that a scanning type signal STP comes to 0 at the testing time of a data bus and comes to 1 at the testing time of a non-synchronous clock bus to supply both of them to the data terminal D of a scanning flip-flop SFF 1. A data selector 12 generates a scanning test clock STCK or clock NSCK 1 applied corresponding to a scanning mode signal SM coming to 1 at the time of scanning test and coming to 0 at the time of usual operation to apply the same to the clock terminal of a flip-flop SFF. Therefore, when the signal SM is brought to 1 and the signal STP is brought to 0 or 1, the testing of a data bus or the testing of the non-synchronous clock and scanning FF can be also adapted to a non-synchronous circuit.

Title: Throttle-opening detector for electronically controlled engine
Inventor: NAKAMURA MITSUO
IPC: G01B7/30
Filed: 1988-04-01
Abstract: PURPOSE:To alleviate the assembling accuracy of a sensor and to improve the detecting accuracy of an opening degree, by storing the output value at the initial time, and computing the opening degree of a throttle baSed on the differences between said value and the output values at the second time and thereafter. CONSTITUTION:A memory means 15 wherein the output value of a throttle sensor is stored is provided in an electronic control apparatus 11 which controls the status of an engine. Said output value is obtained after the preset throttle position at the initial time is detected. The differences betWeen the output value at the initial time and the output values of the sensor at the second time and thereafter are obtained and an actual opening degree is computed in an opening computing means 28. Since the differences between the output value that is initially stored in the memory means 15 and the output values at the second time and thereafter are obtained, the throttle opening is detected as an absolute value. Therefore, the assembling accuracy of the sensor at the initial time is alleviated, and the working man-hours are decreased by that amount. The detecting accuracy of the throttle opening can be improved to a large extent.

Title: Gas injection ophthalmologic apparatus
Inventor: YAMAMOTO MASAMI
IPC: A61F9/00
Filed: 1991-01-23
Abstract: PURPOSE:To enable the keeping of a ripple of a pressure constant with respect to a set pressure as generated in the injection of a compressed gas. CONSTITUTION:This apparatus has first, second and third paths 3, 10 and 11 with respect to a gas storage section 2. The first path 3 is made up of a plurality of shunts 4 and 5, which have shunt valves 6 and 7 respectively. A control section 20 controls the opening or closing of the shunt valves 6 and 7 and an open valve 13 so that a measuring pressure of a pressure measuring section 15 is equal to a set pressure with a pressure setting section 18. This allows the keeping of a value of a ripple almost constant with respect to the set pressure whether the set pressure is large or small. In other words, this enables the keeping of a ripple (rate of change) of the pressure of a gas such as air constant, thereby causing no adverse effect on delicate ophthalmologic surgery.

Title: Semiconductor device
Inventor: TSUNENO HIROSHI
IPC: H01L21/52
Filed: 1983-05-13
Abstract: PURPOSE:To simultaneously secure conductivity and bonding strength by employing a composite structure of the first bonding material layer for securing thermal conductivity and electrical conductivity, and the second bonding material layer for securing bonding strength for the bonding material layer. CONSTITUTION:Since the first bonding material layer 4 includes a large amount of Ag, heat generated by semiconductor pellet 1 is effectively conducted to a ceramic substrate 5 through the first bonding material layer arranged at the center of bonding surface. Meanwhile, the second bonding material layer 5 includes less amount of Ag but a large amount of bonding agent showing a large bonding strength. Therefore, the semiconductor pellet 1 is forcibly adhered to the ceramic substrate 2 by this second bonding material layer. These bonding layers 4, 5 are different with each other in the blending rate but iclude Ag bonding agent. Accordingly, these two compensates for each other in thermal conductivity, electrical conductivity and bonding strength.
